Have you tried a factory reset? Hold in the power and quiet buttons at the same time. While holding in these buttons plug in the power cord. The unit should beep twice. Try that. If the unit still isn't right, call Whistler at 800-531-0004.

It wont detect cops


Does the unit alarm at all? If this your first radar detector? Does it light up and make a sound during the self test? If you have any more questions on this model - email info@whistlergroup.com and the reps at Whistler can help you.

If you have a WHISTLER 1778 (as Cobra is a different brand - like chevy is to Ford), call 800-531-0004 to order a speaker for the Whistler 1778.

Got a whistler xrt-695 from individual. unit powers up goes thru all the frequencie alerts and laser alerts, scans menu to tell what is active. Seems to be perfect. x-band is on, K,Ka, Laser, all of it,...


how long have you had it? Have you had a radar detector before this one? Try a factory reset - hold in the power button and the quiet button, while holding in these buttons plug in the power cord. The unit will beep twice indicating that its reset. Remember the unit is not a "Cop" detector its a radar detector so not all police cars have radar in them and if they do they may not have it turned on.

I have the whistler xtr440 how do i get it to detector cop cars and radar guns


Powering the unit on will autotmatically turn on all the bands. Remember, not all police vehicles have radar and ones that do may not have it on.

I have everything on as far as I can tell and still isnt picking up radars. When I drive past a hospital or automatic door it will go off with out a cop in site so I assume it is the door interfering. but...


First try a factory reset - hold in the power button and the quiet button, while holding in these buttons plug in the power cord, THe unit will beep twice and show FACTORY RESET on the screen, then give it a test.

How good is the whistler 1595se radar detector


That model was made in the late 90's early 2000 and it was the top of the line at that time. It still picks up all the current bands but it will not pick up POP mode radar guns however that the newer Whistler models will do.

Found Whistler Spirit Triband radar detector in my basement. I drove with it and it seems to work; it beeps near radar police and randomly displays a P or C or H or 1 or 7. What do all those things mean?


That model only picks up X , K and the photo radar portion of Ka band, It doens't pick up the full Ka radar guns out there plus it doesn't pick up laser.

H= Highway mode
C= City mode
P= Pulse or instant-on type radar.
The numbers indicate signal strength - higher the number the stronger the signal.

NOT PICKING UP SIGNALS


Radars are like just about anything else you buy these days, you get what you pay for. If you want a cheap but most reliable for the price I would suggest the Whistler XTR-695 *est. price 150 bucks. Although many detectors are prone to being detected by radar detectors (used by law enforcement) this one is a little more likely. So if your state has a ban on radars I wouldnt buy. As far as distance in signal pick up the Valentine One I would go with *est.price400 bucks.

I have a cobra radar dector esd 737 and i sdoesnt pick up cops tell they are like not even a half a mile ahead of you and tips or ideas how to get it to work better


Detecting of radar or lidar emissions depends on mounting of detector.In My experience it is best to mount it just above windscreen wipers.You must check if your detector is visible from license plate level. This is important for laser detection. For other measuring devices it's only important to be visible.Higher mounting facing downwards will reduce false X and K/Ka signals.It will reduce detecing of true as well, so it is all up to you.You must know that laser detecting only covers your car.It d'ont matter if a cop is 300m or 1800m away.X band has a large emission, and it is easily detected.K/Ka band is a pulse emitting and has a lot narrow detecting point.It is effective at max 800m.In ether case speed can be reduced 20-30 km/h in city, and 30-50 km/h on highway.
